Tripyrasulfone, cov qauv tsim muaj nyob rau hauv daim duab 1, Tuam Tshoj Patent Tso Cai Tshaj Tawm No.: CN105399674B, CAS: 1911613-97-2) yog lub ntiaj teb thawj HPPD inhibitor herbicide uas muaj kev nyab xeeb siv nyob rau hauv kev tshwm sim tom qab qia thiab nplooj kho cov nplej. teb los tswj gramineous weeds.
Mechanism ntawm kev ua:
Triazole sulfotrione yog ib hom tshuaj tua kab tshiab uas inhibits p-hydroxyphenylpyruvate dioxygenase (HPPD), uas hloov p-hydroxyphenylpyruvate rau hauv cov zis los ntawm inhibiting cov haujlwm ntawm HPPD hauv cov nroj tsuag. Cov txheej txheem ntawm cov kua qaub dub yog thaiv, uas ua rau muaj qhov txawv txav ntawm plastoquinone, thiab plastoquinone yog ib qho tseem ceeb cofactor ntawm phytoene desaturase (PDS), thiab txo qis ntawm plastoquinone cuam tshuam cov catalytic kev txiav txim ntawm PDS, uas nyob rau hauv lem cuam tshuam rau biosynthesis ntawm carotenoids. nyob rau hauv lub hom phiaj lub cev, ua rau nplooj albinism thiab tuag.
Cov yam ntxwv ua haujlwm:
1. Tripyrasulfone yog ib tug tshiab HPPD inhibitor, uas yog thawj zaug uas HPPD inhibitor yog siv xyuam xim nyob rau hauv post seedling qia thiab nplooj ntoos tshuaj tsuag nyob rau hauv cov nplej teb.
2. Tripyrasulfone tuaj yeem daws tau qhov teeb meem ntawm cov noob resistant thiab multi-resistant barnyardgrass thiab barnyardgrass.
3. Tsis muaj kev cuam tshuam kev cuam tshuam ntawm Tripyrasulfone thiab cov tshuaj tseem ceeb tam sim no, uas tuaj yeem daws cov teeb meem nyuaj tam sim no thiab yav tom ntej ntawm kev tiv thaiv millet thiab barnyard nyom.
4. Tripyrasulfone tuaj yeem sib xyaw nrog qhov tsim nyog ntawm 2 methyl · methazopine los txhim kho kev tswj kev ua haujlwm ntawm cov nyom nyom thiab cov nyom nyom thiab txhim kho cov nroj tsuag kom zoo.
Cov teeb meem xav tau kev saib xyuas:
1. Ua ntej daim ntawv thov, nws yog ib qho tsim nyog yuav tsum tau ua cov kev kho mob kaw kom txo cov nroj tsuag hauv paus thiab nplooj hnub nyoog.
2. Tripyrasulfone tsis tuaj yeem sib xyaw nrog cov tshuaj organophosphorus, carbamate, paclobutrazol insecticides thiab fungicides lossis siv hauv 7 hnub. Nws tuaj yeem siv feem ntau ib zaug thaum lub sijhawm loj hlob ntawm cov nplej.
3. Nws yog txwv tsis pub kis cov chiv 7 hnub ua ntej thiab tom qab thov.
Nws yog txwv tsis pub siv cov bensulfuron-methyl, pentaflusulfurochlor thiab lwm yam ALS inhibitors thiab quinclorac.
4. Cov huab cua yog tshav ntuj, thiab qhov zoo tshaj plaws txau kub yog 25 ~ 35 ℃. Yog tias qhov kub siab tshaj 38 ℃, tsis pom zoo siv tshuaj tsuag. Yog tias muaj nag hauv 8 teev tom qab txau, yuav tsum tau txau ntxiv.
5. Tshem tawm cov dej ua ntej tshuaj tsuag kom ntseeg tau tias ntau tshaj 2/3 ntawm cov nplooj ntoo raug rau cov dej thiab siv cov tshuaj tua kab tag nrho; Tom qab siv cov tshuaj tua kab, cov dej rov qab mus rau 5 ~ 7 cm hauv 24 ~ 48 teev thiab khaws cia rau ntau tshaj 7 hnub. Lub sij hawm tuav dej ntev dua, qhov ruaj khov dua qhov kev tswj xyuas yog.
6. Qee hom nplej indica muaj rhiab heev rau Tripyrasulfone, uas tuaj yeem ua rau cov nplooj albinism, tab sis tuaj yeem rov qab tau, tsis cuam tshuam rau cov qoob loo.
Cov ntsiab lus:
Tripyrasulfone muaj ntau yam tshuaj tua kab mob thiab kev ua haujlwm siab tom qab yub cov nroj tsuag, tshwj xeeb tshaj yog rau Echinochloa crus-galli, Leptochloa chinensis, Monochoria vaginalis thiab Eclipta prostrata, thiab tsis muaj kev cuam tshuam nrog cov tshuaj tua kab tam sim no hauv cov liaj teb, xws li cyhalochlor, pentafluorosulphonachlor thiab dichloroquinoline acid. Nyob rau tib lub sijhawm, nws muaj kev nyab xeeb rau cov noob qoob loo thiab tsim nyog rau kev cog qoob loo thiab kev cog qoob loo ncaj qha, Nws yog tus neeg sawv cev zoo los daws cov teeb meem ntawm cov nroj tsuag tshuaj nyob rau hauv daim teb tam sim no - los tswj resistant barnyard nyom thiab millet, thiab muaj dav thov kev cia siab. Los ntawm ntau qhov kev ntsuam xyuas, nws tau pom tias ntau lub tebchaw uas tau piav qhia hauv Tripyrasulfone muaj kev xaiv zoo rau cov nyom nyom xws li Zoysia japonica, bermudagrass, siab fescue, bluegrass, ryegrass, seashore paspalum, thiab tuaj yeem tswj tau ntau cov nyom nyom thiab cov nyom dav dav. . Cov kev ntsuam xyuas ntawm cov taum pauv, paj rwb, paj noob hlis, qos yaj ywm, txiv hmab txiv ntoo thiab zaub raws li kev sib txawv ntawm daim ntawv thov kuj qhia tau zoo heev xaiv thiab ua lag luam tus nqi.
